The authors developed mathematical model of homogeneous methane-air mix autoignition and combustion in reciprocating engine featuring homogeneous charge-compression ignition (HCCI) process.- Table, 2 ill., 7 ref.
Presented in the article is schematic diagram of engine that enables individual control over particular combustion phases’ duration. Said technique is demonstrated as allowing considerable duration redistribution among different combustion phases.2 Table, 4 ill.
The authors developed computational procedure that enables evaluation of the efficiency of steam injection into turbine inlet duct, with a view to enhance air supply efficiency and thereby engine power output.2 Table, 6 ill., 4 ref.
One of possible ways to reduce engine vibrations is the replacement of conventional materials with ferrite Fe-Cr-Al alloys. The article discusses issues involved therein.4 ill., 4 ref.
The article presents the basics of national technological policies in periodical revision of regulations covering acceptable levels of toxic emissions from marine, locomotive and industrial diesel engines in operation. Said technological policies are being pursued through implementation of new National Standard GOST R 52408 (ISO 8178, Part 2).4 ref.
The article compares known technologies of diesel engine exhaust cleaning. Particular stress is made on liquid cleaning method offered by these authors.3 ill., 10 ref.
The work presents the results of comparative tests of VAZ-1111 engine running on petrol and liquefied gas respectively; recommendations are formulated for tuning of engine ignition and fuel systems.2 Table, 1 ill.
The article discusses aspects of using permanent propylene glycol antifreeze in high-powered engines in order to prevent cavitation-induced failures.3 ill., 5 Table, 12 ref.
The article deals with efficiency of turbochargers used in low-speed marine engines. Discussed are analytical dependences used for efficiency calculation as applied to compressor, turbine, and turbocharger as a whole; furthermore, nomograms are offered for graphic determination of said characteristics.1 Table, 2 ill, 3 ref.
Maintenance system in question is based on risk management principles; i.e., it takes account of particular failures’ consequences.1 Tables, 4 ref.
The article summarizes the results of a research work carried out at TSNITA. In the framework of this research fuel injection system with long operational life was developed that featured precise fuel metering valve operating at pressure of 200 MPa.4 ill.
